[0002] The history of the sailing boat sofa can be traced back to the early 19th century when wealthy people in Europe began to pursue high-quality interior decorations on large yachts and developed various shipboard furniture. Initially, the design inspiration of the sailing boat sofa came from the popular classical sailing boat designs at that time, such as Clipper and Frigate.

[0003] With the continuous development of shipping technology, the sailing boat sofa has gradually evolved into a modern style. The design of the modern sailing boat sofa is no longer limited to black and white color systems and boat-shaped shapes, but pays more attention to practicality, comfort, and aesthetic effects. Modern sailing boat sofa designers usually use high-quality leather, fabrics, and ship timbers to improve the uniqueness and comfort of the product.

[0004] The existing sailing boat sofas generally use leather and fill high-elastic recovery materials such as duck down inside the leather to form the sofa, and the skeletons of the sailing boat sofas are all fixed. When it is necessary to increase the height of the sofa, generally users increase the height of the sofa by adding cushions. However, after increasing the height of the cushions, the overall height of the user sitting on the sailing boat sofa is not comfortable, and the sofa cushions are relatively soft and it is not easy to move on the sailing boat sofa, thus affecting the comfort of the user sitting on the sofa. Therefore, the utility model proposes a new solution to solve the problem of adjusting the sitting height of the sailing boat sofa. Summary of the Utility Model
